Embodiment Construction

[0040]FIG. 14 shows a top view of an improved embodiment of an arm for use with the present invention. Arm 200 includes a semicircular portion 202 and an extending portion 204 attached thereto. Semicircular portion 202 includes two arc portions 230 and 232 and an inner bore 234. The two arc portions 230 and 232 are both recessed or undercut near their ends, as shown by the phantom lines 236 and 238. Thus, the inner bore 234 is not perfectly circular in shape near the ends of arc portions 230 and 232. Ends 240 and 242 of the arc portions 230 and 232, respectively, are well radiused to prevent binding of the arm on the airflow tube during pivoting.

[0041] Extending portion 204 includes two flange portions 206 and 208 on which generally oval depressions 210 and 212 are respectively positioned. Bridge engagement pins 214 and 216 are positioned at far ends of flange portions 206 and 208, respectively, and project, respectively, upwardly and downwardly from the arm 200. A space 218 separa...

Abstract

The present invention discloses an adjustable forehead support for a nasal or full-face mask wherein the forehead support may be adjusted for the different shapes and sizes of a facial profile. The forehead support utilizes a dual-arm system that adjusts the position of the forehead support vis-a-vis the mask and / or airflow tube. The angle of the mask to the face may be adjusted with the present invention.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention generally relates to an improved comfort device to be used with a nasal mask. In particular, the device is useful in combination with masks which are used for the treatment of respiratory conditions and assisted respiration. The invention assists in fitting the mask to the face as well. [0003] 2. General Background [0004] Nasal masks are commonly used in the treatment of respiratory conditions and sleep disorders by delivering a flow of breathable gas to a patient to either assist the patient in respiration or to provide a therapeutic form of gas to the patient to treat sleep disorders such as obstructive sleep apnea. These nasal masks typically receive a gas through a supply line which delivers gas into a chamber formed by walls of the mask. The mask is generally a semi-rigid mask which has a face portion which covers at least the wearer's nostrils. Additionally, the mask may be a full face ma...
